Been racking up miles on the 135i and fixing little things. And finally had a chance to get to the dyno today for some baseline testing. As I've mentioned I've been VERY pleased with the FFTEC twin scroll top mount 5862 turbocharger kit. On road performance and spool is much better than any other combinations I've driven.

Notes:
1) Was not going after any power records so left the tuning very conservative all around. At the same boost levels there is easily another 15hp in this setup with more advance. And no reason this turbo can't be cranked up to 28psi when the trans is ready.
2) It made a lot more power than I was expecting. It's basically on pace with the 6466 at these lower boost levels only with much better spool.
3) If the trans would shift this car would be seriously quick. I'll get to work on that ASAP.

Whoo!!! This turbo will easily hit the 620 goal. Tad more boost with a bit more timing, and you are there! Glad everything is going so swimmingly well with the 135 @Terry@BMS!! All of our emails and communications in regards to the setup seems to have worked out nicelys!

Since Terry had to turn the meth on to run E30 past 17psi I wonder if @Anthony@FFTEC would like to comment on why Shiv was adamant that "meth was only there for cooling purposes and not fueling" on his kits?

In my experience it's just a function of fuel and air/fuel ratio. I'm running ~11.8:1 on E30 and started to see fuel pressure dipping around 500rw. If I was running race gas and 12.5:1 no reason it can't support 600rw or more. Frankly it would be nice to dump the meth kit and run just straight E50 and hit 600rw. But with todays fueling hardware it's just not possible with the air/fuel ratios and steady fuel pressure I'd need to be comfortable with it. Maybe with tomorrows hardware it can be done.
